About Facebook

Founded in 2004, Facebook's mission is to give people the power to share and make the world more open and connected. People use Facebook to stay connected with friends and family, to discover what's going on in the world, and to share and express what matters to them.

This press release contains forward-looking statements regarding our future business expectations, which are subject to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. These forward-looking statements are only predictions and may differ materially from actual results due to a variety of factors including: our ability to retain or increase users and engagement levels; our reliance on advertising revenue; our ability to continue to monetize our mobile products; risks associated with new product development and their introduction as well as other new business initiatives; our emphasis on user growth and engagement and the user experience over short-term financial results; competition; litigation; privacy and regulatory concerns; security breaches; and our ability to manage growth and geographically-dispersed operations. These and other potential risks
and uncertainties that could cause actual results to differ from the results predicted are more fully detailed under the caption "Risk Factors" in our Quarterly Report on Form 10-Q filed with the SEC on November 1, 2013, which is available on our Investor Relations website at investor.fb.com and on the SEC website at www.sec.gov. Additional information will also be set forth in our Annual Report on Form 10-K for the full year ended December 31, 2013. In addition, please note that the date of this press release is January 29, 2014, and any forward-looking statements contained herein are based on assumptions that we believe to be reasonable as of this date. We undertake no obligation to update these statements as a result of new information or future events.

Non-GAAP Financial Measures

To supplement our consolidated financial statements, which are prepared and presented in accordance with GAAP, we use the following non-GAAP financial measures: revenue excluding foreign exchange effect and advertising revenue excluding foreign exchange effect, non-GAAP costs and expenses, non-GAAP income from operations; non-GAAP net income; non-GAAP diluted shares; non-GAAP diluted earnings per share; non-GAAP operating margin; non-GAAP effective tax rate; and free cash flow. The presentation of these financial measures is not intended to be considered in isolation or as a substitute for, or superior to, financial information prepared and presented in accordance with GAAP. Investors are cautioned that there are material limitations associated with the use of non-GAAP financial measures as an analytical tool. In particular, many of the adjustments to our GAAP financial measures
reflect the exclusion of items, specifically share-based compensation expense and payroll tax related to share-based compensation expense, and the related income tax effects, that are recurring and will be reflected in our financial results for the foreseeable future. In addition, these measures may be different from non-GAAP financial measures used by other companies, limiting their usefulness for comparison purposes. We compensate for these limitations by providing specific information regarding the GAAP amounts excluded from these non-GAAP financial measures.

We believe these non-GAAP financial measures provide investors with useful supplemental information about the financial performance of our business, enable comparison of financial results between periods where certain items may vary independent of business performance, and allow for greater transparency with respect to key metrics used by management in operating our business.

We exclude the following items from one or more of our non-GAAP financial measures:

Share-based compensation expense. We exclude share-based compensation expense because we believe that the non-GAAP financial measures excluding this item provide meaningful supplemental information regarding operational performance. In particular, because of varying available valuation methodologies, subjective assumptions and the variety of award types that companies can use under FASB ASC Topic 718, we believe that providing non-GAAP financial measures that exclude this expense allows investors the ability to make more meaningful comparisons between our operating results and those of other companies. Accordingly, we believe that excluding this expense provides investors and management with greater visibility to the underlying performance of our business operations, facilitates comparison of our results with other periods, and may also facilitate comparison with the results of
other companies in our industry.

Payroll tax expense related to share-based compensation. We exclude payroll tax expense related to share-based compensation expense because, without excluding these tax expenses, investors would not see the full effect that excluding share-based compensation expense had on our operating results. These expenses are tied to the exercise or vesting of underlying equity awards and the price of our common stock at the time of vesting or exercise, which factors may vary from period to period independent of the operating performance of our business. Similar to share-based compensation expense, we believe that excluding this payroll tax expense provides investors and management with greater visibility to the underlying performance of our business operations and facilitates comparison with other periods as well as the results of other companies.

Income tax effect of share-based compensation and related payroll tax expenses. We believe excluding the income tax effect of non-GAAP adjustments assists investors and management in understanding the tax provision related to those adjustments and provides useful supplemental information regarding the underlying performance of our business operations.

Assumed preferred stock conversion. As a result of our IPO in May 2012, all outstanding shares of preferred stock were automatically converted into shares of Class B common stock. Consequently, non-GAAP diluted shares and earnings per share for the year ended December 31, 2012 have been calculated assuming this conversion for periods prior to the IPO, which we believe facilitates comparison between periods.

Dilutive equity awards excluded from GAAP. In our calculation of non-GAAP weighted average shares used to compute earnings per share attributable to Class A and Class B common stockholders, we include unvested RSUs for the year ended December 31, 2012, the number of which is substantial due to the terms of RSUs granted prior to 2011. We believe including these awards facilitates comparison between periods.

Foreign exchange effect on revenue. We translate revenue for the current quarter and full year ended December 31, 2013 using prior year exchange rates, which we believe is a useful metric that facilitates comparison to our historical performance.

Purchases of property and equipment; Property and equipment acquired under capital leases. We subtract both purchases of property and equipment and property and equipment acquired under capital leases in our calculation of free cash flow because we believe that these two items collectively represent the amount of property and equipment we need to procure to support our business, regardless of whether we finance such property or equipment with a capital lease. We believe that this methodology can provide useful supplemental information to help investors better understand underlying trends in our business.

For more information on our non-GAAP financial measures and a reconciliation of such measures to the nearest GAAP measure, please see the "Reconciliation of Non-GAAP Results to Nearest GAAP Measures" table in this press release.
